In this outdoor activity (on page 2 of the PDF under GPS: Baseball Activity), learners will investigate the transfer of energy using sports equipment.

In this activity, learners make some music by constructing a kazoo out of a simple plastic drinking straw. Use this activity to explore sound, vibrations, and music.

In this activity on page 2 of the PDF, learners discover how color changes can help scientists distinguish between acids and bases.

In this activity, learners explore how salt water freezes in comparison to fresh water.

In this activity, learners use cardboard bases and track tubes to make a ball run to explore the properties of mass, force, and motion.

In this activity described on pages 2-3 of the PDF, participants debate whether there there's life elsewhere in the universe.

In this activity on page 2 of the PDF (Get Cooking With Chemistry), learners conduct chemical tests on certain powders used in cooking.

In this activity, learners will be working with predictions with a time frame of one week, or longer. Start by planting seedlings.

This is an activity in which learners create magic wands from a variety of materials making their choices by considering what kind of magic they want to make.

In this activity about light and refraction, learners make a lens and magnifying glass by filling a bowl with water.

In this activity, learners determine the shape of an unseen object by bouncing a ball off the object.

In this drawing/mapping activity, learners design plots of land while incorporating positive strategies for improving water quality.

This three-part activity consists of an activity that groups of learners develop themselves, a given procedure, and an optional demonstration.

In this quick optics activity, learners use a dim point of light (a disassembled Mini MagLite and dowel set-up) to cast a shadow of the blood supply in their retina onto the retina itself.

In this activity related to magnetism and electricity, learners discover that a magnet falls more slowly through a metallic tube than it does through a nonmetallic tube.

In this activity, learners make a scale model of the Solar System and learn the real definition of "space." Learners use the online calculator to create an appropriate scale to use as a basis for thei

In this activity (on pages 13-16 of the PDF) learners investigate three mystery samples to see which one contains life. The three samples are sand, sand and yeast, and sand and antacid.

In this interdisciplinary activity, learners create a Space Weather Action Center (SWAC) to monitor solar storms and develop real SWAC news reports.

In this activity, learners work in small groups to match various marine animals with their different environments.

In this activity, learners investigate the speed of chemical reactions with light sticks. Learners discover that reactions can be sped up or slowed down due to temperature changes.
